GOOKING-STOVE.

Specification of Letters Patent No. 18,586, dated November 10, 1857.

To @ZZ whom it may concern:

Be it known that I, JAMES R. HYDE, of the city of Troy, vin the countyof Rensselaer and State of New York, have invented certain new anduseful Improvements in Cooking-Stoves for Burning Bituminous Coal andother Fuel; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to the annexeddrawings, making a part of this specification, in which- Figure 1 is aperspective view of my improved stove-the top-plate being removed andsome other parts broken away; Fig. 2 a longitudinal section, and Fig. 8a front sectional elevation of the same; and Figs. 4, 5 and 6perspective views of its improved grate.

The same letters refer to like parts in all the figures; and the arrowstherein indicate the directions in which both the air which supports thecombustion, and the hot gaseous products thereof, circulate through thestove. p

My improved stove belongs to that heretofore well known class in whichair is admitted into the lire-chamber not only through the grate, butalso above the burning fuel, to promote the combustion of the gasesevolved therefrom.

In my stove, heated air can be admitted into, or prevented from enteringthe fire chamber, above the fuel, simultaneously through both a slit orthe holes, a, along its ont side, `and a slit or small holes, along itsback side, while the draft through the grate is either closed or open;and this is also the case in the stoves upon which mine is animprovement: Yet, in those previously made cooking-stoves, the two setsof holes t and were both supplied with hot air from one and the samechamber or flue, which surrounded the lire-box; so that hot air couldnot be admitted into the firechamber through one of the two sets ofholes, a, b, without at the same time admitting the hot air into thefire-chamber through the other set. But in my improved stove the flue orchamber A, which supplies heated air through the small holes, a, to thefront part of the ire chamber, Y, above the flue X, is distinct from,has no flue connection with, the flue or chamber, B, which supplies hotair to the back part of the fire chamber through the holes b; as well asbeing equally separate from the ash-boxvchamber, C, which furnishes airthrough the grate, F, to the fuel.

The hot-air chamber A, is formed between the front-plate, D, of thestove and the front-plate E, of the fire-box, and has, near its bottom,an opening, c, through the frontplate D, to admit cold air; whichopening is provided with a damper d. The opening c, which alone admitscold air into the iiue B, is also provided with a damper, Cold air isadmitted into the ash-boX-chamber, C, to supply the draft through thegrate, by sliding back the loose hearth-plate, Gr, or through damperedopenings therein, as usual. Thus, in my stove, the three hot-airchambers A, B, and C, are entirely separate, and each is provided with aseparate dampered opening for controlling the admission of cold airthereto, and consequently the discharge of heated air therefrom; so thatthereby the draft into the fire-chamber can be not only through thegrate alone, or through the grate and the two sets of holes a and l); orthrough only these two sets of holes; but also either through the holesa alone, or through the holes alone or through only the grate and theholes Z), or through only the grate and the holes c. This furthercapacity for regulating the admission of hot air into the lire-chamberof the cookingstove above the burning fuel, is of much practicalimportance; for whenever it is desirable to burn the gases which risefrom the burning fuel, only along the front side of the fire-chamber, togive intense heat to the boilers in the front pot-holes of the top-vplate, T, the admission of hot air above the fuel can be conned to theholes a; and whenever it is required to burn the gases only as far backas possible, to give strong heat to the oven H, and boilers in the backpot holes, the admission of hot air above the fuel can be limited to theholes Z9.

All the pla-tes or main pieces of my improved stove are to be cast ofiron and put together in the usual manner of mounting such cookingstoves.

Having thus described my improved cooking stove, I wish it distinctlyunderstood that I do not broadly claim so constructing a stove thatheated atmospheric air can be admitted, at the same or at differenttimes, into the fire-chamber, at different places above or beyond thefuel, from one or both of two separate air-heating chambers, by the useof the dampers by which the admission to or excluded from them, entirelyindependent of the chamber C, by means of the registers c and e, andbeing provided with apertures, a and b, substantially in the manner andfor the purpose specified.
